Abstract

Agriculture 4.0 integrates smart technologies to optimize agricultural management. This work proposes the development of a low-cost remote sensing module for small producers in the north of Paraná, Brazil, using the STM32F411CEU6 microcontroller and the nRF24L01+ module for mesh communication. The system measures temperature, humidity, and pressure using DS18B20, BME280, and capacitive soil moisture sensors via I2C, SPI, and ADC. Powered by a solar cell and Li-Po battery, along with a charge controller, the module acts as a transceiver, sending data to a gateway where it can be stored and analyzed, democratizing access to technology and supporting decision-making in crop management.
